FeAl porous materials, a kind of porous material, is sintered after compression molding of pre-alloyed FeAl powder. As an Intermetallic compound, it takes into account the mechanical properties of metals and the corrosion resistance of ceramics, with stronger sulfur corrosion resistance than metals and higher mechanical strength and thermal shock resistance than ceramics. Therefore, it is widely used in the circumstances such as filtration and purification in high-temperature sulfur containing environment, for example, Fly Ash filters in Shell coal gasification and char filters in EGSA coal gasification.

Stainless steel is a common metal material resistant to air, water and other corrosion. Stainless steel porous material is a kind of porous material, which is sintered after compression molding by stainless steel alloy powder with good heat resistance and corrosion resistance. It is widely used in gas-solid, liquid-solid separation and fluidization distribution in the fields of petrochemical, coal chemical, food, medicine and so on. The products such as adsorption desulfurization filter of SZorb, raw oil filter, residue filter, oil slurry filter and aeration cone are included.

Superalloy is a metal material based on iron, nickel and cobalt, which can work for a long time above 600℃ with certain stress. With the performance of excellent high-temperature strength, good oxidation and thermal corrosion resistance, comprehensive performance of stainless steel, such as fatigue resistance and fracture toughness, superalloy is mainly applied to gas filtration, powder recycling under the high temperature, such as high-density ethylene catalyst filter.

High flux metal membrane is compound porous material of wire mesh or metal fiber felt and metal powder. It makes full use of the toughness and flux of the support layer of wire mesh, and combined with the high-precision film of surface metal powder to form a high-flux, high-precision compound porous material with high-temperature and corrosion resistance. It has a wide range of application in the field of high-flux and low-resistance high-temperature gas dedusting, which is an ideal substitute for organic baghouse dedusting and electrostatic precipitator.
